negated character class

[massimilianodesimone]

It seems to me that Reggy does not detect negated character classes properly.
The regex \b[^a-b]{4}\b matches four letter words that do not contain the range [a-b].

Above, Reggy matches the words 'been' and 'beck', which are four letter but contain the letter 'b'.

If I tick the "Match Case" check box, Reggy does not match anymore the words 'bean' and 'beck'.

similar issue with a negated class
any non-word character and not a space should not include the letter 'a'
